ANTISKID-TIRE AND STUD THEREFOR.

Specificatitn of Letters Patent. Patented Ai g. 16, 1910.

Application filed July 19, 1909. Serial 1%. 508,380.

To allwhom, it may concern:

Be it known that 1-, CHARLES S. BnEBE, a citizen of the United States, residing at Racine, Racine county, Wisconsin, haveinvented certain new and useful Improvements in Antiskid-Tires and StudsTherefor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same.

This invention relates to certain improve ments in anti-skid tires and studs therefor; and the objects and nature of the invention will. be readily understood by those skilled in the art in the light of .the following explanation of the accompanying drawings illustrating What I now consider my preferred embodiment from anion other for mations and constructions within the spirit and scope of my invention.

It has been found in practice that the period or life of usefulness of certain types of pneumatic tires provided along their treads with projecting exterior anti-skidding or armor studs, is to a. certain extent, limited by the lifeof the studs, or in other words, that the studs will wear out or wear off before the tire itself is worn out, thereby renderin the tire practically useless, or requiring if it be practical. to do so) dismarr tling or separation of the tire from its shoe, tread or 0()V8l,'1BlHOV21l of the worn studs or rivets, application of new studs or rivets and reassembling of the parts of the tire.

It isgan object of the invention to provide attachable or renewable heads or wearing surfaces for anti-skidding studs or rivets,'

. which can be readily applied to stud or rivet heads and which can themselves be renewed as they wear out, whereby the anti-skidding studs of tires can be indefinitely renewed as they wear out so that the cover or tread of the tire can be used until rendered useless by wear without having its period of service 0 (form a wearing or protective surface or o y. Y

A further object of the invention is to provides new article of manufacture consistmg of an open or ap rpximately U-shaped anti-skidding stud a apted to he slipped laterally onto the head of the tire rivet and then clipped thereon by bending to embrace the rivet head. 4

The invention consists in the article, inthe combination and arrangements, as set forth. v

Referring to the accompanying draw ings :--Figure1, is a sectional perspective of a portion of a tire cover or tread armored. with tire rivets provided with my improved attachable anti-skidding studs, some of the studs holding a tightly compressed body of soil, and others being shown without the soil. Fig. 2, is a sectional View through a stud applied to a rivet, showing the earth in the a stud. Fig. 3, is a top plan view enlarged of a stud before being applied and clipped.

with the rivets at their inner ends suitably clenched or otherwise secured. For instance, I show the inner ends of the rivets passed through and clenched or upset on washers 3, and thereby securely fastening the rivets in the tire tread withtheir heads at the outer surface thereof; In the specific example illustrated, the rivet heads 2, are approximately flat, being slightly rounded and comparatively thin or small although I do not wish to thus limit-my invention as the permanent rivet heads canbe of any suitable size, shape or formation permitting substantially application of the attachable anti'skidding studs thereto.

The anti-skidding studs of my invention are adapted for application to the exterior rivet heads, and in the particular example illustrated, each stud consists of a single 111* tegral U or horse shoe shaped block or body 4., of suitable hard metal of such malleability that'it can be clipped or bent as hereinafter described. The body is rounded or semi-circular at the closed end with two approximately parallel legs extending therefrom and spaced apart a suflicient distance to receive the rivet head 2, between them. At

proximately L-shaped in cross section and as though formed by an L shaped or angular bar bent into U-shape although these attachable studs can be formed by castings, drop forging, bending metal bars or otherwise. The studs are driven laterally onto the rivet heads with the shoulders or flanges thereof caught under the rivet heads, said flanges wedging tightly between the outer surface of the tire tread and the under faces of the rivet heads; The studs are driven onto the rivet heads until said heads are completely seated in the closed ends of the heads and 30 are closed together or approximately tothen the opposite ends or legs of each stud ge ther, by any suitable implement, thereby cllpping the studs on and completely inclosingthe rivets.

The studs can be formed of any suitable vertical length or thickness to project the desired distance outwardly beyond the surface of the tire'tread and to form cups or sockets of any suitable depth opening out- 40 wardly beyond the rivet heads and closed at their inner ends by the rivet heads. The attachable studs, thus form cups or-sockets which pick up and gather dust, soil or dirt from the road, and the dirt fills and is tightly packed and compressed in these cups, forming a hard wear resisting body 9, in each stud. The bodies 9, relieve the attachablestuds of much of the wear. and whena stud is so Worn that it will no longer hold and retain a body of dirt or soil therein, such stud can by a suitable implement, have its legs spread so that the Worn stud can be removed from the rivet head and a new stud be clipped thereon. The rounded inner ends or faces of the studs not only preventing cuttin or damaging of the tire tread but also aid in wedging'and driving the studs on the rivet heads.

It is obvious that various changes in form, shape and dimensions, and that variations and modifications in the modes oflapp1ication mightbe resorted to without departing from the spirit and scope of hence do not wish to limit exact construction shown.

my invention, myself to the What I claim is 7 1. An approximately U-shap-.d attachable antiskidding stud for tires, the ends of the stud adapted to be bent toward each other for securing the stud.

2. An attachable compressible anti-skidding stud for tires having a side entrance opening, said stud being approximately L- shaped in cross section.

3. A headed tire rivet provided with an anti-skidding stud embracing said head' and projecting outwardly beyond the same to form a dirt cup closed at its inner end by said head, said stud having an opening to receive said head and being compressed to close said opening against passage of the head.
